This presentation will explore threat actors including insiders, cybercriminals, hacktivists and nation-states. We will dissect how these actors operate and analyze their techniques to better understand what makes each group successful. This presentation will translate the "who, how and why" of cyberattacks. We will identify multiple "old school" and modern-day threat vectors and organize attacks by motives like financial and political. Each threat actor type will be explored in detail with real-life use cases and personal accountants based on my work in security in over 50 countries and 6 continents for the last 20 years.
